反応手順

Following the above procedure, Suzuki coupling of 3.4 g of 7-acetyl-12-bromo-7H-dibenzo [a,g]carbazole and 3.8 g of 4-(1-phenyl-1H-benzo [d]imidazol-2-yl) phenylboronic acid were stirred together in 30 ml of toluene. To this was added 0.01 g of tetrakis(triphenylphosphine)palladium, 2.7 g of potassium carbonate and 10 ml of aqueous ethanol were added and refluxed under nitrogen for 6 h. The reaction was quenched with water and the toluene layer was removed and passed through a celite column. The organic layers were combined and then evaporated in a rotary evaporator under vacuum to yield 4.6 g of 7-acetyl-12-[4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl]-7H-dibenzo [a,g]carbazole as a white solid.
